Thread: stability problems
Hello Newsgroup I have stability problems with my Postgres 6.4 database. I am using PHP4.0.4 and get access to the db. Sometimes when about 10-20 clients are using the website the postgres deamon shuts down and the message "no backend cache" appears. The processor ist at 60%-80% and about 10-15 postgres processes are on my linux machine. So what can i do ? My postgres-command is: /usr/lib/pgsql/bin/postmaster -B 2048 -i -o -F -D/var/lib/pgsql Thanks Lars
Upgrade to 7.1 as soon as it's out (shouldn't be long now).. I successfully migrated a 6.4 database to a 7.1 database while 7.1 was in the early beta stages, a few minor problems but the entire process only took half an hour to complete.. Good luck! -Mitch Software development : You can have it cheap, fast or working.

I have had over 50 clients running simultaneously with no problems with Postgres 7.0.3 & PHP 4.0.4pl1 on Linux. Please download and install a newer version. If you need any help doing this then email the list. Don't forget to the dump the database(s) first. Brent __________________________________________________ Do You Yahoo!?

Hello,
I'd like to ask, if anyone has written a tool, allowing to
dump the tables (both the schema and the data), basing on the
'base' table_name, specified by the user. The tables that the database
consists of, form a tree (as a result of the relations), so what I'm
looking for is a program (script), issuing the 'DROP *', 'CREATE *', 'COPY
FROM ' commands in the proper order. pg-dump dumps the whole 'tree' - I'd
like to be able to specify myself the 'root' of this 'tree'.
I realize, that my influency in English makes the description more vague,
than it should be :) sorry.
regards, mark
PS. The reason why I feel I'm in need of suach a thing is that in general,
when I try do pg_dump the database I'm working with, I get the errors -
sometimes the inherited constraints seem to be unappropriate (both in
terms of definitions and with their names), the COPY FROM clause sometimes
also (starting with a particular row) generates error. Analyzing this
would be much more simple, if I focus on the 'subset' of the whole dump -
200+ tables for me is just too big bunch of info.
The other reason is, that all the tables form (logically) several parts -
I keep them together, because the parts interact (joins occur) between one
another. And I'd like to be able to dump a specific logical part.
